Wow, so did you use him for sex? Wow. What is that like? Sorry, to sound shocked but some of our spouses are being loyal to their OP. Isn't that ironic?
I have no OP and, as far as I know, my H doesn't have one either.
Like a lot of other separated folks on this board, we're clearly still physically attracted to each other and I was surprised at how strongly that attraction could override my emotional misgivings about our M. And it kind of threw me for a loop.
Did I use him? It sure feels like it. Did he use me? Possibly.
Overall it felt strange. A friend of mine told me that having a good physical relationship with my H is either something to build on, or something to say goodbye to.
